Hello again,

im working with a Model using two kinds of nodes.
In emfatic the model looks like this (just a short piece of it).

@gmf.node(label="identifier", border.width="2", border.color="0,0,0", size="130,50", figure="rectangle", label.icon="false")
class Goal extends StandardNode {
  ref AwayGoal[*]#ReferencedGoal isReferencedByAwayGoals;
}

@gmf.node(label="identifier", border.width="1", border.color="0,0,0", size="130,50", label.icon="false", figure="rectangle")
class AwayGoal extends StandardNode {
  ref Goal[1]#isReferencedByAwayGoals ReferencedGoal;
  attr String AwayGoalModuleIdentifier;
}

@gmf.node(label="identifier")
class StandardNode {
  attr String identifier;
  attr String path;
  attr String content;
}


So i got a bidirectional relation between AwayGoal and Goal. Each AwayGoal must be assigned to one Goal.
And each Goal can be assigned to many AwayGoals.

This should work also between 2 instances of my Model.

Now i wont a Listener on my AwayGoals Objects.
Everytime when the ReferencedGoal is changed it should do something.
Here the specific Attribute of the AwayGoal should be set to the identifier of the referencedGoal.
I do this like this in my AwayGoalImpl Construction.

protected AwayGoalImpl()
  {
    super();
	EContentAdapter adapter = new EContentAdapter() {
		public void notifyChanged(Notification notification) {
			if(notification.getFeature() instanceof EReferenceImpl
					&&notification.getNewValue() != null)
			{
				Goal localReferencedGoal = (Goal) notification.getNewValue();
				TransactionUtil.getEditingDomain(notification.getNotifier()).getCommandStack().execute(
						new SetCommand(TransactionUtil.getEditingDomain(notification.getNotifier()),
								(EObject)notification.getNotifier(),
								GsnModelPackage.Literals.AWAY_GOAL__AWAY_GOAL_MODULE_IDENTIFIER,
								localReferencedGoal.getIdentifier()));
			}
		}
	};
	this.eAdapters().add(adapter);
}


This works great now if i create these references inside a single instance which means one file.

If i now create the AwayGoal in one file(default.gsnmodel) and the Goal in the other(default2.gsnmodel),import the resource default2.gsnmodel in default.gsnmodel and set the Goal in my AwayGoal it still works.
But if i want to open the other File(default2.gsnmodel) now, containing the referencedGoal i got the following popup.

Cannot open input element.
Value 'gsnModel.impl.AwayGoalImpl@5c76d06a (eProxyURI: platform:/resource/testing/default.gsnmodel_diagram#_8ecCkCpZEeGsuMg9LAaJ2A)' is not legal. (platform:/resource/testing/default2.gsnmodel_diagram, 5, 118)


And the following exception:

You understand that an EContentAdapter attaches itself to all objects in
the containment tree, not just to a single object, right.

You understand that by not calling super, you're completely defeating
the purpose of a content adapter?

Why are you testing against an implementation class rather than against
EReference?

It seems likely you'll be executing a command in the middle of executing
the command that caused this notification. Probably not much good will
come of that.

If you have bidirectional references between files you need to save both
files when you add such a reference. Are you doing that?
